I guess I can answer some of these questions:

Any pics of it with a tetra?

The spear, hook, red bar, and ring all work together to grasp and hold a tetra very well. The cylinder is just set back in the arm to help with the cg. It is connected to the hook with a shaft. The cylinder is 12 in. I think. The lower red bar functions as a fulcrum that makes the tetra rotate up in to the ring. The hook grabs the apex of the tetra, and pulls it back into the ring. The straping on the sides stops tetras from getting really caught on the arm.

I will see about getting a pic of it holding one or possibly some vid if I can.

I think at weigh in it was 114.1, but we have some mods to do at vegas so that will go up a bit. We havent measured it, but I think it can go 10ft straigh up in the air, though that isnt really usefull.

All of the robot, exept for shafts and gears are aluminum.

The window motor was added at first for more tourqe, but we discovered that it does a good job at preventing backdriving(some times too good of a job).

We haven't ever had any problems with defensive bots getting in our wheels. They all have one major problem...... they have to catch up with us first



Thanks for all the complements guys!
